Answer 1

Explicație pas cu pas:

${x}^{2} \leqslant 16 \iff \ {x}^{2} \leqslant {4}^{2} \\ \implies 1 \leqslant x \leqslant 4$

A = {1; 2; 3; 4}

${x}^{3} \leqslant 64 \iff \ {x}^{3} \leqslant {4}^{3} \\ \implies 1 \leqslant x \leqslant 4$

B = {1; 2; 3; 4}

=> A = B

A ∪ B = {1; 2; 3; 4}

A ∩ B = {1; 2; 3; 4}

A \ B = Ø

B \A = Ø
